IMPROVEMENT IN PLOWS.

Specificationforming part of Letters Patent No. 190,538, dated May 8,1877; application filed December 13, 1876.

' To all whom it may concern:

Be it known that we, lVIATHEW M. BEARD and GEO. W. PURGELL, of BlackHawk, in the county of Carroll and State of Mississippi, have inventedcertain new and useful Improvements in Plows, 86G. and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inWhich- Figure l is a perspective view of a plow constructed with ourimproved frame-piece. Fig. 2 is the frame-piece detached. Fig. 3 showsthe under side of the plow-blade; and Figs. 4 and 5 show various otherattachments which may be used with our invention.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to the construction ofa frame-piece to whichvarious farm implements may be attached, thus saving the cost ofseparate frame-pieces, substantially as hereinafter more fully shown anddescribed.

In the drawings,- Ais the framepiece. This is made preferably of cast orwrought iron, in one piece, and it consists of one flat horizontal andone curved upright piece, the latter being placed at an acute angle tothe former, with which it forms a point, a. The flat piece (in thedrawing indicated by the letter b) forms, when a plow attachment isused, the land-side, as will be seen at Fig. 1. The frame-piece A issecured to the under side of a plow-beam, B, having handles 0 O, and abrace,D, passes from the rear end of the plowbeam to the land-side 12,thus holding the frame-piece securely in position.

The upright piece c of frame-piece A is somewhat flattened in front,where it has two or more slots, d d, and on one side it has a rabbet, e.F is the plow attachment, which is made, share and mold-board, in onepiece.

On one side it has a stout flange, f, fitting into the rabbet e inframe-piece A, and projecting in front of the share, so as to form thepoint t., The flange 7, being ot'considerable thickness, it follows thatthe plow-point which is usually the weakest, and, at the same time, themost exposed, part of a plow, can be made much stronger than isordinarily the case.

This share has a series of perforations, i 1', corresponding with slotsd, thus enabling the entire piece F to be attached by means ofscrew-bolts, the flange f fitting intogroove or rabbet 0, thus securingthe plow attachment very solidly in position.

In Figs. 4 and 5 are shown various other attachments which may be usedwith advantage in combination with the frame-piece A. These, and avariety of other agricultural implements, may be secured to theframe-piece A in the same manner as the plow attachment, viz., withscrew-bolts and nuts-provided, of course, that they have perforations iarranged to correspond with the slots din the framepiece.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States The frame-piece A, consisting offlat bottom-piece 12, forming the land-side, and curved upright c, thelatter having slots at d and rabbet c, in combination with the plowattachment F, having perforations i and flangef, the latter projectingso as to form the point t, substantially as and for the purpose shownand specified.

In testimony that we claim the foregoing as our own invention, we havehereto affixed our signatures in presence of two witnesses.
